Kikyo and Inuyasha in “Unfinished Business”

Kikyo

(thinking) Naraku's miasma is persistent. Even Kagome's purification was not enough.

Inuyasha

Kikyo!

Kikyo

Inuyasha, I take it you followed the Soul-collector?

Inuyasha

Kikyo, what do you intend to do with Midoriko's soul?

Kikyo

(pulls her robes back from her shoulder, revealing her poisoned wound) This is what Naraku inflicted upon me at Mount Hakurei.

Inuyasha

But weren't you healed?

Kikyo

For a short time, yes. But as you can see, the wound has now reopened. This is the reason why I have taken Midoriko's soul. Using it is the only option I have. Otherwise, I'll be consumed by the miasma; this body will return to the earth before I defeat Naraku. Even though Midoriko's soul is dead, I know it will help me stay alive long enough to complete my task. Midoriko was priestess who had died, slaying demons. In many ways, you could say that we share the same soul. (the Soul-Collector drops Midoriko's soul into Kikyo's body) I am sure she will understand my reasons for doing this.

Inuyasha

Kikyo! (picks her up, thinking) Her wound is healing.
